DeprecationWarning: .data is not a valid RequestInit property, use .body instead

I get following warning: `(node:82174) [https://github.com/node-fetch/node-fetch/issues/1000 (request)] DeprecationWarning: .data is not a valid RequestInit property, use .body instead`

When calling following code:

```
const publisher = google.androidpublisher({ auth: authClient, version: 'v3' })

const packageName = this.getPackageName()

const editsInsertRes = await publisher.edits.insert({
packageName,
requestBody: {
expiryTimeSeconds: String(new Date().getTime() + 2),
},
})
```

Stacktrace:

node v.20.3.1

Inizia dal percorso dell'avviso in node_modules/node-fetch/src/request.js, quindi segui la richiesta attraverso gaxios/src/gaxios.ts e lo stack di autenticazione Google mostrato nel trace. Riproduci la richiesta Android Publisher su Node v20.3.1 e determina dove viene introdotta la proprietà `.data` non valida. Il lavoro è completato quando la richiesta non emette più questo avviso di deprecazione.
